What to know about sweet potato
Despite the name, sweet potato is not a nightshade. It belongs to the morning glory family (Ipomoea batatas), while the white potato is the actual nightshade (Solanum tuberosum), so people avoiding nightshades can usually eat sweet potato freely. Its real trigger is oxalate: sweet potato is high in oxalate, with roughly 97 mg in a medium one, which matters for anyone prone to calcium-oxalate kidney stones.
Watch for
- High in oxalate, around 97 mg per medium sweet potato, a meaningful amount for anyone managing calcium-oxalate kidney stones or on a low-oxalate diet
- Not a nightshade: it is in the morning glory family, unlike the white potato, so nightshade-sensitive people generally tolerate it
- Moderate salicylate and moderate polyols, so a large portion can also add up for sensitive guts
